What is the current state of Swappable Consensus and Re-Genesis

Question

I've found these two open issues:

• Re-Genesis #7458
• Swappable Consensus #1304

and would be interested if there is more practical guidance on an example basis?

Answer 1

Swappable consensus was a potential solution to the lifecycle of parachains when they lose their parachain slot, allowing them to swap their consensus to some solo-chain system, and then back to a parachain if they won another auction.

However, given the introduction of parathreads as a much better solution to this problem, I believe swappable consensus is not a feature being worked on anymore. Obviously the expert in this case is @rob.

I am not sure about the specific state or thinking around re-genesis. Best to keep multiple questions to multiple posts.

However, it seems at a high level, the process of re-genesis can be done with tools like fork-off-substrate. Beyond that, halting one chain and starting another seems like a coordination issue that is solved off-chain or with some custom client logic.
